description The invention discloses a device for testing performance of a cooling fan for a rail vehicle cooling system. The device is characterized by comprising an air tunnel, a pressure stabilizing chamber, a simulation unit and a driving measurement unit; the air tunnel is connected with the pressure stabilizing chamber to provide the pressure stabilizing chamber with air; the simulation unit and the driving measurement unit are arranged within the pressure stabilizing chamber; the simulation unit comprises front/rear vertical walls, left/right vertical walls, a base plate and a heat dissipation assembly; shutters are mounted on the front/rear vertical walls; the driving measurement unit comprises a motor, a speed measuring motor, a horizontal torquemeter, a gear box, a vertical torquemeter, a universal shaft, a fan mounting shaft and a mounting base. The device is capable of simulating actual running working conditions of a rail vehicle and thus more accurately testing the pneumatic performance of a cooling fan in actual running.
